The ruleset for the ColecoVisionADAM.com High Score Club. Last updated 24 August 2026.

• On certain days a game or games will be announced and a topic will be started for the round. Rounds run for one or two weeks and end on Sundays, usually at 11 EST. Exceptions will be noted in the topic for that round.
• To join the club, just enter a score. Use the submission form or post it in the round's thread - either reaches a curator. You need a free SmartFORUM account to enter a score, but not to play or to read the boards.
• Only your best score in a round counts. Enter as often as you like - a better one replaces your place on the board and a lower one changes nothing, so there is never a reason not to try again. Nothing you enter is deleted; the board simply shows one line per player.
• Emulators are permitted, including the one on this site - most rounds can be played in your browser with nothing to download. Please do not use the save/load feature of any emulator to come back later and finish a game in progress. High scores should be from a single playing session.
• Games played using the AtGames ColecoVision Flashback will not be accepted - original hardware and emulation only. Using the AtariMax multi-cart is acceptable.
• Pausing a game is acceptable for short periods, to allow for bio breaks.
• Screenshots of your score are not necessary but are encouraged for higher scores. For bonus points, HSC records, contests and exceptional high scores for each round, they are required. If you play in the browser here the screenshot is taken for you when you submit, so there is nothing to photograph or upload.
• Post your scores in the thread for the actual game. Please create a new post for each score - do not update an existing post with a new score.
• Please do not cheat or abuse bugs and glitches in the games to your advantage.
• Use the same skill level as posted, so that all scores are comparable.
• Everyone who rolls a score will be tied for first place. Unless noted in the thread you do not have to continue playing after you roll a score, unless you choose to do so. Exceptions will be noted in the topic for that round.

The scoring system encourages every player to try for their personal best, because it is proportional. The player with the highest score in a game takes first place and wins 100 points. Everyone else is allocated points based on their score relative to the top score. Points are rounded to the nearest integer.

Ties

If a tie occurs for first place then both, or all, of the tied players receive 100 points. Everyone else is allocated points relative to the top score as usual.

A tie for any other position does not affect the scoring: the tied players receive the same number of points, and nobody below them is moved. So the only way a player's points can be reduced is if the top score is increased.

This is what makes the system work for everybody. Exceptional players can keep raising the top score, pushing everyone else's points down; and a player lower in the ranking can always earn more points simply by beating their own previous best.

Rounds are played on games the archive already holds a copy of - most of the original ColecoVision library, and a great deal of the homebrew that has since been released freely. Members put games forward on the nomination page, and the search there only offers games that qualify.

Games still being sold are not played here. CollectorVision and Opcode Games continue to make and sell their titles, and the club will not put one up as a round. The archive lists them because they are part of the ColecoVision record; that is a different thing from inviting a few hundred people to press play on a copy. If you want one of those games, buy it from the people who made it - they are still going, and they earned it.

This is a rule about what the club chooses to offer rather than a technical measure - anything a browser can run, a browser has a copy of. It works because the club decides what to put up, not because anything is locked.

Most rounds can be played in your browser on this site - nothing to download and no account needed just to play. It is the same ColecoVision emulation the museum's game pages use, running the round's cartridge.

When you press Submit on the submission form after playing here, two things are recorded along with your score:

• A screenshot of the game screen, taken at that moment. It saves you photographing a television, and it is what a curator reads the number off.
• How long the emulator ran, as a frame count. It is a sanity check and nothing more - a large score after a few seconds of play is worth a second look. It is not proof of anything and it never decides a score on its own.

Neither replaces a curator looking at your submission, and neither is collected if you play on real hardware or in your own emulator - in that case attach a photograph instead, or just post the score in the round's thread. Playing on original hardware is a first-class way to enter this club, not a second choice.

The ColecoVision High Score Club is just for fun and bragging rights. Please do not cheat, and do not abuse bugs or glitches in the games to your advantage. If you are suspected of cheating in any way, your score will be removed from the HSC.

If you have any questions or comments, send a PM to RGDiRocco on the SmartFORUM and you will get a reply as soon as possible.
